1.) A carburetor, a carbureted intake manifold, a new ignition system, a modified fuel pickup in the gas tank and an aftermarket electric fuel pump or a mechanical fuel pump and new timing cover with the provision for the mechanical fuel pump, some custom fab'd fuel lines in the engine bay at minimum... lots of electrical removal (buy an EVTM to see what wires and sensors you can eliminate).

2.) Fox Mustang Shorties, unequal length. The stock HO tubular manifolds (basically a header) fit nicely with a stock engine. Don't go larger than 1 5/8 on the primaries, I'd recommend 1 1/2 inch on a stock engine.

3.) 3.55's are good for a daily driver. 3.73's are okay too, especially if you stay under 65 mph for the most part.

4.) I'd wait on the ignition until you do the carb conversion. Stock replacement cap and rotor should be okay until then. If you'd like, try to get brass terminals in the distributor cap (they don't corrode as bad as aluminium ones).

why carb an efi car? your mileage will go to shit!
3.55 or 3.73 gears and a trac lock are good fun
use shory headers for a mustang and the h pipe

My thoughts exactly.

I average 17 with a carb on the highway. With a b cam in it no less. Depends on the engine set up.

if it's a DD, I strongly suggest leaving it it EFI.
doing a full HO conversion will get you into the low 16s in the 1/4 mile if you have 3.55s.
or if you can find a good set of GT40 heads, those are good.
an HO intake is better than the stock one, but an Explorer or GT40 is better from what I hear.

Summit Racing sells some nice Ceramic coated shorty headers for 302s that are a great value..I got em on my car. 240bux and they are VERY thick and heavy duty compared to the other shorties out there.

for gears...I got 3.55s..I like em but my hwy mpg with my EFI motor going about 70-75mph was 21.5.
city with them was as high as 18. I swear I noticed a difference with a K&N filter on the stock air cleaner setup..went from getting 17 in the city to over 18.

You may also have problems getting it through emissions with a carb. Not sure the laws there in Chicago though.

wow guys u real came thou this time lots of good info!! the whole carb thing was just a idea i had wasnt to sure of real doing it but it sounds like alot more work then i thought!! iam trying to keep my engine org till i swap out where i can pick and chose what i want i am serious about the headers and gears thou really all iam trying to get is my car to sound a little more louder right know i got stright pipes with some cherry bombs!! has far has emissions my car dosent ever have to go again so that a plus i was thinking about getting ride of 2 of the 4 cats

o can i use a b303 cam on a stock motor this just a question

[1987cp]

Sure, long as you make some basic changes like getting a speed-density HO ECM and realize that you won't realize the full benefit of the bigger cam with your E6 heads.

[gadget73]

the B cam isn't well suited for a heavy car, and I doubt the stock EFI will run well with it. Mustang mass air stuff will do it but with those lousy heads, you're going to end up with a huge turd of a performer.

[torquelover]

If you do anything, do an HO conversion, as said before. Well documented, and good reliable performance. If it were easier and cheaper for me, I would swap my carb setup for EFI.

Stock HO cam or Explorer cam works great in these boats. Ford letter cams aren't great, and none are really worth bothering with unless you do a HO swap.
